To calculate the potential energy gained by lifting the suitcase onto the bench, you can use the equation PE = mgh, where m is the mass (14 kg), g is the acceleration due to gravity (9.8 m/s^2), and h is the height (40 cm = 0.4 m).
PE = (14 kg) * (9.8 m/s^2) * (0.4 m)
PE = 54.88 Joules
Therefore, the potential energy gained when Nan lifts the suitcase onto the bench is 54.88 Joules.
